Good Luck! Ninomiya-kun

ご愁傷さま二ノ宮くん

High schooler Shungo Ninomiya, a capable martial artist, shares a large house with his mercenary older sister Ryouko. When Ryouko takes in the Tsukimura siblings, Shungo ends up living with Mayu, a young succubus sent to overcome her terror of men and learn to control powers that knock out any male who gets near her. Her incubus brother Mikihiro moves in too, and Shungo's home turns into a comedy of clashing supernatural houseguests.
